ABSTRACT:
On an aircraft it is proposed that the orientation (pitch and roll attitudes and heading) of a support structure (10), such as the structure supporting the optical head of a head-up control system, be regulated by means of an inertial unit (16). The said unit is firstly placed on its previously regulated rack (14) in the hold of the aircraft and the three orientation parameters are measured. The inertial unit (16) is then placed on an intermediate support (26) fixed to the support structure (10) and the orientation parameters are again measured. Following the comparison of the two measurements, the orientation of the support structure (10) is corrected so as to cancel out their differences.
